Every so often when weather conditions are just right, strange apparitions begin to form by the entrance to Raymore Park. These are the shapes of homes that lined Raymore and Gilhaven Drives until Hurricane Hazel brought devastation to the area in 1954. The houses at this location were untouched by the flooding but were purchased and demolished as a precaution. The basements were filled in and levelled. Part of an original concrete pathway still survives. The shape of the basements can be seen because the fill was different to the surrounding soil causing a variation in the plant cover. Based on the same principle, archaeologists often use aerial photographs when looking for ancient settlements.
